| 摘 要： | 建立了双频振动压实机一土壤系统的力学和数学模型，在试验基础上确定了模型中的参数值和相关系数。将数学模型转换为状态方程，利用SIMULINK仿真框图进行数值仿真，得到了压实机参数和土壤参数变化与压实效果的关系。以压实机对地面作用力最大为目标函数，以试验所得主要参数的取值范围作为约束条件，对压路机的参数匹配进行了优化。

| Abstract: | The mechanical and mathematical models of double-frequency vibration Compactor and soil systemwere made. The model parameters and the coefficient correlation were determined based on experiments. Then the author transforms the mathematical model into the equation of state and carries on the value simulation using the SIMULINK simulation diagram, obtained the compaction machine parameter and the soil parameter change and the compaction effort relations. The match of roller parameters were optimized using the largest ground force as objective function and the value range of main parameters obtained by a trial as restrictive conditions. |
